Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

青少年在网络空间构筑了基于共同兴趣和偏好的“新社群”。网络社群内部的圈层化趋势加强了青少年之间的联系与共鸣,在一定程度上重塑了他们的社会认知和伦理判断。然而,这种圈层化也带来了新型场域对伦理空间的冲击、圈层区隔对伦理关系的界分、特定惯习对伦理实践的影响和微观规训对伦理意识的裹挟等问题,将他们置于伦理挑战的情境中进行考量。鉴于此,创构主流舆论传播新格局、释放网络圈层整合共振力、激活多元话语互促生命力、注重外部治理和内部自律的统一性,对于网络社会治理和构建网络空间命运共同体具有重要意义。
