In 2019,ChemPlusChem included an article by Sivalingam, Soumya; Debsharma, Kingshuk; Dasgupta, Ayan; Sankararaman, Sethuraman; Prasad, Edamana. Formula: C10H7I. The article was titled 《Effect of Slip-Stack Self-Assembly on Aggregation-Induced Emission and Solid-State Luminescence in 1,3-Diarylpropynones》. The information in the text is summarized as follows:

Co-facial stacking can result in aggregation-caused quenching (ACQ) in conjugated organic luminogens. This study provides an attractive ‘slip-stack’ self-assembly approach which can eliminate the occurrence of ACQ. The obtained results from steady-state and time-resolved optical studies, along with X-ray diffraction and computational studies demonstrate aggregation-induced emission enhancement (AIEE) of a donor-π-acceptor based 1,3-diarylpropynone, namely 1-(naphthalenyl)-3-(pyren-1-yl)prop-2-yn-1-one (PYNAP). Unlike the monomer, which exhibits poor photoluminescence in solution (Φf = 2% in ACN), the twisted manifold of PYNAP allows the orientation of the mols. in a slip-stack fashion during the course of aggregation, which not only avoids a direct co-facial arrangement, but also induces augmented rigidity, leading to restricted intramol. rotation (RIR) and enhanced emission quantum yield (Φf = 5% in ACN/H2O). The aggregation behavior of PYNAP’s congener, 1-phenyl-3-(pyren-1-yl)prop-2-yn-1-one (PYPH) reinforces the hypothesis that slip-stack assembly is a useful strategy for AIEE in polycyclic hydrocarbon luminogens. In the experiment, the researchers used many compounds, for example, 1-Iodonaphthalene(cas: 90-14-2Formula: C10H7I)

1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
