Synthesis of Alkyl- and Alkyloxy-Substituted 2,3-Naphthalocyanines
摘要:
Four novel differently substituted 2,3-dicyanonaphthalenes (6-(hexyloxy)-2,3-dicyanonaphthalene (5), 5-(hexyloxy)-2,3-dicyanonaphthalene (11), 6,7-bis(hexyloxy)-2,3-dicyanonaphthalene (17), and 5,8-diheptyl-2,3-dicyanonaphthalene (22)) and the respective peripherally substituted (bis(tert-butylisocyano)-2,3-naphthalocyaninato)iron(II) compounds 23-26 were synthesized and characterized.

Naphtho[2,1-b:3,4-b′]bisthieno[3,2-b][1]benzothiophene derivatives exhibiting a hole mobility of up to 0.25 cm2 V−1 s−1 show promise as useful building blocks to construct next-generation high performance organic semiconductors.

properties. The selective synthesis of unsymmetrical systems, particularly phthalocyanines, has remained a significant unmet challenge. Porphyrin‐phthalocyanine hybrids offer the potential to combine the favorable features of both parent structures, but again synthetic strategies are poorly developed. Here we demonstrate strategies that give straightforward, controlled access to differentially substituted

Series of structurally related substituted triphenylene derivatives were designed and synthesised to interrogate key features which determine mesophase formation and stability, and to challenge the general conclusions previously proposed by us and others. It is apparent that no single, simple principle can be universally applied.

A novel, clean and efficient route to unsymmetrical triphenylene mesogens has been developed using palladium-catalysed cross-coupling reactions involving arylboronic acids.
Macrocycle-based architectures are of importance in synthetic chemistry. Here, a novel parallelogram metallomacrocycle Fe2(LA)2 with reversible structural transformation was designed and synthesized. The template-free metalla[2]catenane [Fe2(LA)2]2 could be obtained by changing the concentration and has been monitored on the basis of NMR analysis. By redesigning the metallo-ligand, a catenane-like
