Abstract

Two thiophene-vinyl-diketopyrrolopyrrole (TVDPP)-dye-based mesopolymers, PTVDPP-TT and PTVDPP-BT, were synthesized under near-room-temperature conditions. These mesopolymers exhibit non-halogenated solution processability, high molecular coplanarity, narrow bandgaps (approx. 1.2 eV), short π-stacking distances (<3.6 Å), and excellent crystallinity. They demonstrate high hole mobilities of 0.83 and 0.93 cm² V⁻¹ s⁻¹, respectively, for optoelectronic applications in field-effect transistors.

高性能有机场效应晶体管用噻吩-乙烯基双酮吡咯染料基介聚合物的近室温高效合成

在近室温条件下合成了两种噻吩-乙烯基二酮吡咯（TVDPP）染料基介聚合物PTVDPP-TT和PTVDPP-BT。这些介聚合物具有非卤化溶液可加工性，高分子共平面性，窄带隙(约为。1.2 eV)， π堆积距离短（<3.6 Å），结晶度优异。它们在场效应晶体管的光电应用中分别表现出0.83和0.93 cm2 V−1 s−1的高空穴迁移率。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
