Quick update on the relevant patent applications. The application for the 'diamondoid' patent has been approved and the patent was issued (no. 11924101). Adding the diamondoid groups to the chromophore allows for higher concentrations of the chromophores in the material, and facilitates easier alignment of them (better poling efficiency), both of which result in higher r33.

Application 18/078337 (for use of high glass-transition temperature (Tg) polymers combined with specific solvents that allow 'mechanical' poling) received a notice of allowance on 1/04/24, meaning it's been reviewed and approved. As described:

"Resulting liquid crystalline properties provide a mechanical anisotropic effect allowing for the formation of a non-centrosymmetric chromophore-polymer matrix without the application of an electric field. In accordance with various embodiments described herein, a sufficient electro-optic coefficient (r33) can be induced mechanically, alleviating the need for the application of poling temperature and electric field, typically 170° C. & 100 v/pm. The liquid crystalline properties
and the lyotropic compositions allow for milder processing conditions and, thus, higher poling efficiency."

This is saying that the chromophores can be arranged without clumping (bad for r33) without applying an electric field, and that high temperatures are also not needed for poling. When Lebby said "high temperature" in the recent PR, he was referring to using materials with high Tg (the temperature at which a polymer starts to soften), meaning the Perk won't degrade at typical manufacturing and operating temperatures.

There is a delay in issuing the patent due to a modification requested by LWLG, which appears to be related to providing some improved figures (photos of chromophores which are blurry in the original application). This will not stop it from being issued.

I assume this is what you are calling Pk6.
