Co-luminescence Effect of Heterometallic Terbium–Gadolinium Hybrid Molecular Materials Constructed by Covalent Grafting

Abstract  In this paper, 2-chlorobenzoic acid (CBA) and 2-chloronicotinic acid (CNA) were modified by 3-aminopropyl-trimethoxysilane (APMS) to afford corresponding organic–inorganic monomers (CBA–APMS and CNA–APMS) with
