AIE (aggregation-induced emission)-active molecules hold promise for the labeling of biomolecules as well as living cells. The study of the binding modes of such molecules to biomolecules, such as nucleic acids and proteins, will shed light on a deeper understanding of the mechanisms of molecular interactions and eventually facilitate the design/preparation of new AIE-active bioprobes. Herein, ...

Aromatic dicationic compounds possess antimicrobial activity against a wide range of eucaryotic pathogens, and in the present study an examination of the structures-functions of a series of compounds against fungi was performed. Sixty-seven dicationic molecules were screened for their inhibitory and fungicidal activities against Candida albicans and Cryptococcus neoformans. The MICs of a large ...

The design of small molecular ligands able to bind with DNA is pivotal for the development of diagnostic agents and therapeutic drugs targeting DNA. Carbazole-derivatives are potential agents against tumors and opportunistic infections of AIDS. Here, two carbazole-derived dicationic compounds, DPDI and DPPDI, were designed, synthesized and characterized using NMR, IR and MS. The DNA binding pro...

Reaction of the imidazolium-substituted diphosphete-diide, (IPr)2C2P2 (IDP), with GeCl2∙dioxane and KBArF24 [(BArF24)− = tetrakis[(3,5-trifluoromethyl)phenyl]borate)] afforded dicationic spherical-aromatic nido-cluster [Ge(η4-IDP)]2+ ([1]2+) (IPr 1,3-bis(2,6-diisopropylphenyl)imidazolium-2-ylidene). This complex is a rare heavy analogue elusive pyramidane [C(η4-C4H4)]. [1]2+ undergoes two rever...

trans-Bis(alkynyl)palladium complexes, trans-[(PEt3)2Pd(-CtCC{dO}NR2)2] (NR2 = NMe2 (2a), N(CH2)4 (2b)), were synthesized by two different methods: (a) by copper-catalyzed reaction of HCtCC(dO)NR2with [PdCl2(PEt3)2] under basic conditions and (b) by treatingHCtCC(dO)NR2 with AgNO3 followed by transmetalation of the alkynyl ligand from silver to [PdCl2(PEt3)2]. The reaction of AgCtCC(dO)NMe2 (3a...
