Photoredox processes induced by metal-tometal charge transfer (MMCT) excitation have a t­ tracted much attention in recent years [1-4]. These processes may be exploited for applications in arti­ ficial photosynthesis and photocatalysis [5, 6], They also facilitate our understanding of optical and thermal electron transfer in general [7, 8], A point of particular interest is the relationship be­...

In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...

Security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. For this reason, security is always of managers, planners, architects and urban designers' interest. Solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes and h...
