Furthermore the dye molecules are arranged in a parallel and stacked manner within the aggregates resulting in a hypsochromic shift [47].
Nevertheless, the substitution of dye 6e by a NO 2 group (6d) showed a largest hypsochromic shift of 30 nm.
Nevertheless, the substitution of dye 6e by a OCH 3 group (6b) showed a largest hypsochromic shift of 21 nm.
Next, from the date in Table-3, these dyes are further characterized by the hypsochromic shift observed with an increase solvent polarity (negative solvatochromism).
It is apparent that the bands corresponding to n-Pi and charge transfer transition [19] exhibit a hypsochromic shift in DMF relative to THF except for dye 6d.
The Q band can be either blue-shifted (a hypsochromic shift) or red-shifted (a bathochromic shift) caused by change in the structure of the phthalocyanine.
This can be explained in terms of electrostatic repulsion of positive charges between the metal Pc and the surfactants destabilizing the LUMO of the MgPc nanoparticles and hence giving rise to a hypsochromic shift.
This specific interaction of the dopant with the host polymer influences the PAs properties and the following changes were observed: (i) bathochromic shift of photoluminescence (PL) emission band in DMA solution, (ii) blue shift of absorption bands in DMA solution, (iii) hypsochromic or bathochromic shift of PL emission band in m-cresol solution, (iv) blue shift of absorption bands in MC solution, (v) solubilization of the polymers in organic solvent, by protonation of the polymers.
As the curing proceeds, the fluorescence emission spectra of the probes exhibited hypsochromic spectral shifts due to the increases in matrix microviscosity.
