Abstract
Compared with other sequence structure polymers, alternating polymers usually have several unique properties, but their properties are more sensitive to changes in structure. By investigating the relationship between the structure and properties of alternating polymer chains, polymers with desired properties can likely be synthesized. In this study, a series of alternating copolymers of 1,1-diphenylethylene (DPE) derivatives and styrene derivatives, which exhibit nontraditional intrinsic luminescence (NTIL), are synthesized using living anionic polymerization. By changing the bridge plane structure of the DPE derivatives and the substituent groups of the styrene derivatives, the rigid chain structure of the alternating copolymers containing styrene derivative with a large steric hindrance is altered, and this change is observed by the altered fluorescence properties. Based on the results from experimental tests and theoretical simulations, copolymers with bridge plane structures have higher fluorescence emission intensities; moreover, a balance is observed between the electronic and steric hindrance effects of substituents on the fluorescence intensities, and polymer chains that are too rigid cause a decrease in the fluorescence intensities. Thus, the influence of the chain structure on the fluorescence properties of NTIL polymers cannot be disregarded.

Abstract
The stability-related issues arising from the perovskite precursor inks, films, device structures and interdependence remain severely under-explored to date. Herein, we designed an ionic-liquid polymer (poly[Se-MI][BF4 ]), containing functional moieties like carbonyl (C=O), selenium (Se+ ), and tetrafluoroborate (BF4 - ) ions, to stabilize the whole device fabrication process. The C=O and Se+ can coordinate with lead and iodine (I- ) ions to stabilize lead polyhalide colloids and the compositions of the perovskite precursor inks for over two months. The Se+ anchored on grain boundaries and the defects passivated by BF4 - efficiently suppress the dissociation and migration of I- in perovskite films. Benefiting from the synergistic effects of poly[Se-MI][BF4 ], high efficiencies of 25.10 % and 20.85 % were exhibited by a 0.062-cm2 device and 15.39-cm2 module, respectively. The devices retained over 90 % of their initial efficiency under operation for 2200 h.
