Abstract
New polymeric materials containing dinuclear double-stranded zinc(II) helicate with bis(1,2,3,7,9-pentamethyldipyrrin-8-yl)methane have been prepared on the basis of poly(methyl methacrylate) and tetraethoxysilane. The zinc(II) complex [Zn2L2] retains its fluorescence properties in a poly(methyl methacrylate) film. The photostability of [Zn2L2] in poly(methyl methacrylate) is higher by a factor of ≈2.5 than in the benzene solution. Conditions have been found for the preparation of [Zn2L2]-doped silicate matrix based on tetraethoxysilane via the sol–gel method. The [Zn2L2] complex in the tetraethoxysilane solid matrix shows a weak fluorescence with its maximum at λ = 545–549 nm.
