Cationic Polymerizations

In this work, eleven heteroleptic copper complexes were designed and studied as photoinitiators of polymerization in three-component photoinitiating systems in combination with an iodonium salt and an amine. Notably, ten of them exhibited panchromatic behavior and could be used for long wavelengths. Ferrocene-free copper complexes were capable of efficiently initiating both the radical and cationic polymerizations and exhibited similar performances to that of the benchmark G1 system. Formation of acrylate/epoxy IPNs was also successfully performed even upon irradiation at 455 nm or at 530 nm. Interestingly, all copper complexes containing the 1,1′-bis(diphenylphosphino)ferrocene ligand were not photoluminescent, evidencing that ferrocene could efficiently quench the photoluminescence properties of copper complexes. Besides, these ferrocene-based complexes were capable of efficiently initiating free radical polymerization processes. The ferrocene moiety introduced in the different copper complexes affected neither their panchromatic behaviors nor their abilities to initiate free radical polymerizations.

Single-crystalline GeS nanoribbons were synthesized by chemical vapor deposition for the first time. The nanoribbon photodetectors respond to the entire visible incident light with a response edge at around 750 nm and a high responsivity, indicating their promising application for high performance broadband visible-light photo-detection.

Excellent Photocatalytic Activity

CuS hexagonal nanosheet/graphene was fabricated by a facile one-pot microwave-thermal method. The samples possess excellent photocatalytic activity for degradation of organic pollutant under visible light. The high photocatalytic activity was attributed to the deposition of CuS hexagonal nanosheet onto graphene. CuS nanosheet serves as a transporter which efficiently inhibits the recombination of the photo-induced charge carriers in the nanocomposites. The developed method demonstrates a facile approach towards the synthesis of two-dimensional semiconductor-graphene nanocomposites with excellent photocatalytic performance under visible light.
