The facile tuning of the gate size and the chemical functionalization of zeolitic imidazolate framework-8 (ZIF-8) were achieved by the postsynthetic modification with 3-amino-1,2,4-triazole. The resulting amine functionalized ZIF-8 particles enabled CO ₂ selective adsorption and further chemical modifications.

Ladder-like structured polysilsesquioxane with carbazole groups showed unexpected high photo- and electroluminescence efficiencies both in solution and solid states due to its rigid silicone ladder structures, which efficiently isolated the carbazole groups and thus suppressed their excimer formations by inter- and intramolecules.
