Phthalocyanines (Pcs) are 18-electron π-conjugated macrocyclic ring systems with proven activities in diverse fields, including pharmaceuticals and catalysis. These demonstrated often alluded to as their fascinating photophysical photochemical dispositions, which usually dependent on molecular structures. However, many of these molecules suffer from aggregation due π–π stacking have limited ins...

A new class of polymeric hole-transport materials (HTMs) are explored by inserting a two-dimensionally conjugated fluoro-substituted pyrene into thiophene and selenophene chains. The broad plane “Lewis soft” selenium atoms not only enhance the π–π stacking HTM molecules greatly but also render strong interaction with perovskite surface, leading to an efficient charge transport/transfer in both ...

Chemical vapor deposition is a conventional synthesis method for growing large-scale and high-quality two-dimensional materials, such as graphene, hexagonal boron nitride, transition-metal dichalcogenides. For organic films, solution-based methods, inkjet printing, spin coating, drop micro-contact are commonly used. Herein, we demonstrate general wafer-scale continuous, uniform, ultrathin (2–5 ...

Chromophores [1] with light absorption at long wavelengths in the visible or even in the near infrared are becoming increasingly attractive [2]. Commonly, such a bathochromic absorption is realized with very large π systems; see for example ref. [3]. Bathochromically absorbing smaller molecules are more difficult to obtain [4], but can be developed by balancing substituent effects in conjugated...

Abstract The chemistry of hoop-shaped π-conjugated molecules has increased dramatically in recent years. We present here a computational modeling photoinduced electron transfer processes series host–guest complexes Twin1 , Twin2 and Twin3 double nanohoops with C 60 fullerene. According to our findings, charge from cycloparaphenylene (CPP) fragments is energetically favorable occurs on sub-nanos...

Molecular packing motifs in solid states is the dominant factor affecting the n-channel organic field-effect transistors (OFETs). However, few systematic researches were performed in the different extensions of π-conjugated molecules with the uniform substitution effecting the molecular packing motifs. In this manuscript, OFET devices based on three latterally expanded rylene diimides end-funct...
