Regio-Specific N-Alkyl substitution Tuning the Molecular Packing of High-Performance Non-Fullerene Acceptors

The rapid development of non-fullerene acceptors (NFAs) with strong near-infrared absorption has led to remarkably enhanced short-circuit current density (Jsc) in organic solar cells (OSCs). The NFAs based on benzotriazole...

Terminal alkyl substitution in an A–D–A-type nonfullerene acceptor: simultaneous improvements in the open-circuit voltage and short-circuit current for efficient indoor power generation

Terminal alkyl substituents in IDIC nonfullerene acceptors improve light absorption, crystalline packing and charge mobility in films.

Mixed N-aryl/alkyl substitution favours an unusual tautomer of near-infrared absorbing azacalixphyrins

This work depicts the synthesis of a new azacalixphyrin presenting both aryl and alkyl substituents. The joint experimental and theoretical study supports that the substitution pattern favour an unusual 5–7 tautomer.

Effect of n-alkyl substitution on Cu(ii)-selective chemosensing of rhodamine B derivatives

Substitution with n-alkyl chains of different lengths (Cn > 7) at the N-terminus of rhodamine hydrazide probes led to variation in associated parameters in their Cu(ii)-selective chemosensing.
