Abstract

Diketopyrrolopyrrole (DPP) and its derivatives have been widely studied in the past few years due to its intrinsic physical and chemical properties, such as strong electron-withdrawing, deep color, high charge carrier mobility, strong aggregation, good thermal-/photo-stability. In the 1970s, DPP was developed and used only in inks, paints, and plastics. Later, DPP containing materials were found to have potential other applications, typically in electronic devices, which attracted the attention of scientists. In this feature article, the synthesis pathway of DPP-based materials and their applications in organic field-effect transistors, photovoltaic devices, sensors, two photo-absorption materials, and others are reviewed, and possible future applications are discussed. The review outlines a theoretical scaffold for the development of conjugated DPP-based materials, which have multiple potential applications.

Obiettivo e tipo di lavoro

È una mini-review (Frontiers in Chemistry, 2020, sezione Organic Chemistry; autori Bao, Li, Dai, Tang, Shi, Geng, Deng, Hua) che offre una panoramica d'insieme sulla sintesi dei materiali a base di dichetopirrolopirrolo (DPP) e sulle loro applicazioni. Gli autori osservano che esistevano review dedicate a singoli ambiti (OFET, sensori, celle solari) ma non una trattazione complessiva, e si propongono di colmare questa lacuna.

Contenuto in sintesi

Introduzione. I DPP sono pigmenti rossi commercializzati negli anni '80, usati in origine in inchiostri, vernici e plastiche. Il nucleo biciclico con due ammidi (lattami) e due carbonili è fortemente elettron-povero, il che lo rende un accettore ideale per materiali coniugati donatore-accettore (D-A); le molecole mostrano forte impilamento π-π e aggregazione. Il primo polimero semiconduttore con DPP flanked da tiofene per OFET è del 2008 (mobilità lacune 0,1 e elettroni fino a 0,09 cm2/V s).

Sintesi. Farnum e collaboratori (1974) ottennero per primi un DPP difenil-sostituito con bassa resa; Iqbal et al. (1988) misero a punto la via a singolo stadio tra un nitrile aromatico e un dialchil succinato, con rese elevate. Sono descritti DPP isomeri e flanked da fenile, piridile, tienile, furanile, selenofenile, tienotiofenile, con colori dal rosso al blu. I DPP non sostituiti sono insolubili per i forti legami a idrogeno N-H···O=C nello stato solido; l'alchilazione dei lattami rompe questa associazione e rende il materiale solubile, mentre la bromurazione dei gruppi aromatici fornisce monomeri per la polimerizzazione. I primi polimeri con DPP (Stille, 1993) furono seguiti da Suzuki, polimerizzazione elettrochimica e Buchwald.

Applicazioni. (i) OFET: mobilità regolabili da p-canale (lacune 6,63 cm2/V s) a n-canale (elettroni 7,89 cm2/V s) variando il rapporto tra unità CNTVT e SVS; fino a 12 cm2/V s con ingegneria delle catene alchiliche; valore massimo riportato 26 cm2/V s (lacune) con tetrametilammonio ioduro nel film. (ii) OPV: PCE 4,0% (Voc 0,61 V) con DPP-bitiofene e PC70BM nel 2008; 5,5% (Voc 0,8 V) sostituendo il bitiofene con fenile; celle non-fullerene fino a 12,08% con oligomeri DPP assorbenti nel NIR. (iii) Sensori: film polimerico per fluoruro con limiti di rivelazione 10^-6-10^-8 M, sonda per cianuro (da verde fluorescente a rosso spento), derivati idrosolubili NIR in cellule CHO con resa quantica intracellulare del 34%. (iv) Assorbimento a due fotoni (TPA): sezioni d'urto fino a 1200 GM per piccole molecole, 859 GM per polimeri, 1140 GM per oligomeri con emissione indotta da aggregazione. (v) Altro: elettrocromismo, rivestimenti epossidici con maggiore stabilità UV, materiali trasportatori di lacune per perovskiti, emettitori OLED con EQE 12,1%.

Risultati e conclusioni principali

I DPP uniscono forte carattere elettron-attrattore, planarità, aggregazione, ampio assorbimento (fino al NIR), alta mobilità e buona stabilità termica e fotochimica. Gli autori suggeriscono di esplorare i DPP flanked da selenofene (migliore planarità) e piridile (LUMO basso), allargare la coniugazione e modificare le catene alchiliche.

Figure, schemi e tabelle notevoli

L'articolo ha solo due figure: Figura 1 (panoramica delle applicazioni dei materiali DPP) e Figura 2 (sintesi dei pigmenti DPP e principali gruppi flanked). Non ci sono tabelle.

Collegamento con la tesi

La tesi cita questa fonte alla riga 77 (sezione 1.1), nella frase sulle caratteristiche fisiche del DPP (punto di fusione elevato, forte insolubilità, colore rosso) rimaste inosservate finché i ricercatori Ciba-Geigy non ne svilupparono i derivati. Per approfondire servono l'Introduzione (storia commerciale come pigmento) e la sezione Sintesi (insolubilità dovuta ai legami a idrogeno e soluzione tramite alchilazione). Va notato che l'articolo non cita un punto di fusione preciso né il nome Ciba-Geigy: questi dettagli provengono da altre fonti e non sono verificabili qui.

• Sez. 1.1 Dichetopirrolopirroli (tesi.md r. 77): Le particolari caratteristiche fisiche di questa molecola, tra cui un punto di fusione molto elevato (>350 °C), la fortissima insolubilità e la tipica colorazione rossa, rimasero inosservate finché i ricercatori della Ciba-Geigy Specialty Chemicals Co. non ne svilupparono i primi derivati, ispirandosi alle analogie strutturali con altri pigmenti già noti[1].
