Matrix dependence of blue light emission from a novel NH2-functionalized dicyanoquinodimethane derivative (2006)
Journal Article
Szablewski, M., Bloor, D., Kagawa, Y., Mosurkal, R., Cole, J., Clark, S., …Palsson, L. (2006). Matrix dependence of blue light emission from a novel NH2-functionalized dicyanoquinodimethane derivative. Journal of Physical Organic Chemistry, 19(3), 206-213. https://doi.org/10.1002/poc.1020

The reactions of primary and secondary amines with (cyclohexa-2,5-diene-1,4-diylidene)-dimalononitrile (TCNQ) lead to mono- and disubstituted dicyanoquinodimethane derivatives and fluorescence emission has been observed for several of these compounds...

Absolute measurements of photoluminescence quantum yields of solutions using an integrating sphere (2006)
Journal Article
Porrès, L., Holland, A., -O. Pålsson, L., Monkman, A., Kemp, C., & Beeby, A. (2006). Absolute measurements of photoluminescence quantum yields of solutions using an integrating sphere. Journal of Fluorescence, 16(2), 267-273. https://doi.org/10.1007/s10895-005-0054-8

We demonstrate that absolute measurements of the photoluminescence quantum yield of solutions can be made using an integrating sphere and a conventional fluorimeter. With this method the need for measurements against a luminescence standard is overco...

A small/wide-angle X-ray scattering and grazing incidence diffraction study of comb-shaped supramolecules of conjugated poly(2,5-pyridinediyl), acid dopant and hydrogen bonded amphiphilic side chains is reported. In solution, polymers are dissolved r... Read More about Diffraction analysis of highly ordered smectic supramolecules of conjugated rodlike polymers..

Local field and aggregation dependence of the micro- and macroscopic optical non-linearity of zwitterionic molecules (2003)
Journal Article
Cross, G., Hackman, N., Thomas, P., Szablewski, M., Pålsson, L., & Bloor, D. (2003). Local field and aggregation dependence of the micro- and macroscopic optical non-linearity of zwitterionic molecules. Optical Materials, 21(1-3), 29-37. https://doi.org/10.1016/s0925-3467%2802%2900108-8

When a dipolar-conjugated molecule can lower its energy through gaining aromaticity, there can be a quite dramatic evolution of its polarisation properties dependent on the local reaction field generated in its environment. We have studied conjugated... Read More about Local field and aggregation dependence of the micro- and macroscopic optical non-linearity of zwitterionic molecules.

Polarized luminescence from self-assembled, aligned, and cleaved supramolecules of highly ordered rodlike polymers (2002)
Journal Article
