Constructing a High-Efficiency MoO3/Polyimide Hybrid Photocatalyst Based on Strong Interfacial Interaction
TL;DR: It is confirmed by X-ray photoelectron spectroscopy, electron paramagnetic resonance, and Fourier transform infrared that the strong interaction between BMO and PI leads to the formation of a Mo-N coordination bond that results in a large number of Mo5+ cations in BMO/PI.

TL;DR: Investigations on the optical and electronic properties of MQDs/PI composites reveal that the strong quantum confinement effect of MqDs results in a blue-shift of the absorption band edge of PI, and the interfacial electronic interaction between M QDs and PI improves the charge transfer rate of MZD/PI.

In situ growth MoO3 nanoflake on conjugated polymer: An advanced photocatalyst for hydrogen evolution from water solution under solar light
TL;DR: In this article, a series of MoO3/PI composite photocatalysts were prepared via a facile in situ solid-thermal approach, and the measurements for the optical and electronic properties of these composites confirmed that MoO 3 nanoflakes on the surface PI not only induce the absorption of visible light but also suppressed the radiative recombination of charge carriers.

A (001) dominated conjugated polymer with high-performance of hydrogen evolution under solar light irradiation
TL;DR: A two-dimensional imide-based conjugated polymer with a preferred (001) orientation was constructed by solvent-induced assembly and an excellent stability were achieved due to tunnelling charge transport between the neighbouring molecular sheets.

Controllable Conformation Transfer of Conjugated Polymer toward High Photoelectrical Performance: The Role of Solvent in Induced-Crystallization Route
TL;DR: In this paper, polyimides with different conformation (dendritic, spherulitic, and laminar) were synthesized in different solvents and the strong solvent-dependent conformation variation is intimately related to the specific interactions between the polymer chain and solvent molecules that have a primary driving force for the chain diffusion and rearrangement.
