DOI: 10.1021/acs.nanolett.1c04519
Abstract: Generally speaking, for a semiconductor, the temperature dependence of excitonic emission corresponds to that of its band gap. However, an anomalous behavior is exhibited by the excitonic luminescence of diamond where as the temperature increases… read more here.

DOI: 10.1039/c9qo00294d
Abstract: An aryl-amine attached to the meso-position of the BODIPY skeleton quenches the fluorescence. The observed edge fusion creates a new heterocyclic subunit simultaneously increasing the efficiency of emission. The quantitative deprotonation of meso NH functionality… read more here.

DOI: 10.1039/d1ra07444j
Abstract: Geometrical structure, stability and cooperativity, and contribution of hydrogen bonds to the stability of complexes between chalcogenoaldehydes and water were thoroughly investigated using quantum chemical methods. The stability of the complexes increases significantly when one… read more here.

DOI: 10.1039/d2dt00390b
Abstract: A novel CdII-based two-fold interpenetrated metal-organic framework (MOF), namely {[Cd2(BTDB)2(4,4-bpy)]·DMF}n (JXUST-14), (H2BTDB = 4,4'-(benzo[c][1,2,5]thiadiazole-4,7-diyl)dibenzoic acid and 4,4-bpy = 4,4-bipyridine), has been prepared and characterized. Single-crystal structure determination reveals that JXUST-14 has a tetranuclear cluster based… read more here.

Abstract: A terbium-based metal-organic framework, namely {[Tb2(ADIP)(H2ADIP)(HCOOH)(H2O)2]·2DMF·2H2O}n (Tb-MOF, H4ADIP = 5,5'-(anthracene-9,10-diyl) diisophthalic acid), was synthesized and characterized. The single-crystal structure analysis shows that the Tb-MOF crystallizes in the C2/C space group in the monoclinic system and… read more here.
