The research of new multifunctional materials, as those undergoing spin crossover (SCO) and luminescent properties, is extremely important in the development of further optical and electronic switching devices. As a new step towards this ambitious aim, the coupling of SCO and fluorescence is presented here following two main strategies: whether the fluorescent agent is integrated as a part of the main structure of a 3D SCO coordination polymer {FeII(bpan)[MI(CN)2]2} (bpan = bis(4-pyridyl)anthracene, MI = Ag (FebpanAg), Au (FebpanAu)) or is a guest molecule inserted within the cavities of the 3D switchable framework {FeII(bpb)[MI(CN)2]2}·pyrene (bpb = bis(4-pyridyl)butadiyne, MI = Ag (FebpbAg·Pyr), Au (FebpbAu·Pyr)). The magnetic, calorimetric, structural, UV-Vis absorption and fluorescent characterizations were performed confirming the occurrence of a SCO-fluorescence interplay in the studied compounds. Moreover, the relevance of the intrinsic or extrinsic nature of the luminescence on the efficiency of the interplay is discussed on the basis of the available information.

Three new mixed-ligand divalent coordination polymers (CPs) {[Zn3(L)(1,4-bdc)3]·2DMF}n (1), {[Zn2(L)(2,6-ndc)2]·3DMF}n (2) and {[Cd2(L)3(2,6-ndc)2]}n (3) [L?=?9,10-di(pyridine-4-yl)anthracene, 1,4-H2bdc?=?1,4-benzenedicarboxylic acid, 2,6-H2ndc?=?2,6-naphthalenedicarboxylic acid] have been prepared and well characterized by elemental analyses, infrared spectroscopy, single-crystal X-ray diffraction techniques, powder X-ray diffraction patterns and thermogravimetric analyses. The crystal structure analyses of coordination polymers (CPs) reveal that all the complexes 1–3 have the three-dimensional (3D) coordination networks. The structure of 1 can be simplified as a sqc3 3D 8-connected framework with the point symbol of (424·64). Particularly, in the presence of the linear 2,6-H2ndc auxiliary ligand, a double-deck interpenetrating pcu 3D network of 2 is assembled by 6-connecting framework with the point symbol of (412·63). Complex 3 exhibits a ttd 3D 5-connected net with a point symbol of (46·64). Further, the solid-state luminescent properties of the complexes 1–3 were measured and studied at room temperature.
