Multifunctional Pt( ii ) metallomesogens exhibiting luminescence and proton conductivity in the mesophase near room temperature
New asymmetrical pyridine- and isoquinoline-functionalized bis(pyrazolate) Pt( ii ) metallomesogens have been engineered and designed to exhibit multifunctional properties in terms of mesomorphism, photoluminescence and ionic conductivity near room temperature.

It is also noteworthy that the luminescence typically decreases with temperature, whereas the ionic conductivity increases to values of the order of 10
