Abstract
The synthesis and crystal structure of Cu(II) complex of a binucleating tridentateligand 1,3-bis [N,N-bis(2-picolyl)amino]propan-2-ol (I) is being reported. The two chelatingbispicolylamine arms in I are tethered by a 2-hydroxypropyl group with Cu(II) coordinatingin a slightly distorted square planar geometry to give [Cu2 [...] Read more.

Molecularly imprinted polymers (MIP) exhibiting high selectivity and affinity tothe predetermined molecule (template) are now seeing a fast growing research. However,optimization of the imprinted products is difficult due to the fact that there are manyvariables to consider, some or all of which can potentially impact upon the chemical,morphological and molecular recognition properties of the imprinted materials. This reviewpresent a summary of the principal synthetic considerations pertaining to good practice in thepolymerization aspects of molecular imprinting, and is primarily aimed at researcher familiarwith molecular imprinting methods but with little or no prior experience in polymersynthesis. The synthesis, characteristic, effect of molecular recognition and differentpreparation methods of MIP in recent few years are discussed in this review, unsolvedproblems and possible developments of MIP were also been briefly discussed.

Abstract
Using electronic absorption spectra and thin layer chromatography, the reactionof 2,2-diphenyl-1-picrylhydrazyl (DPPH) with O2•, HO•, HO, and HOO anions and freeradicals revealed the formation of the para-nitro- and para-hydroxy-derivatives of 2,2-diphenyl-1-picrylhydrazine (DPPH-H) and of DPPH fragmentation products(diphenylamine, tetraphenylhydrazine).

Using electronic absorption spectra and thin layer chromatography, the reactionof 2,2-diphenyl-1-picrylhydrazyl (DPPH) with O2•, HO•, HO, and HOO anions and freeradicals revealed the formation of the para-nitro- and para-hydroxy-derivatives of 2,2-diphenyl-1-picrylhydrazine (DPPH-H) and of DPPH fragmentation products(diphenylamine, tetraphenylhydrazine). The reaction of DPPH with the O2•anion-radical(from KO2 in benzene solution at room temperature in the presence of 18-crown-6 ether) ispseudo-first-order during the first 25 minutes. Full article
