Abstract:
A method is disclosed for preparing metal-free phthalocyanines having the formula (I) by reaction of an ortho-phthalodinitrile of formula (Ia) in an inert solvent having a boiling temperature of at least 120 °C (under normal pressure) in the presence of ammonia. In formulae I and Ia, the variable n can take the value of 1, 2, 3 or 4 and the radicals R denote a five- or six-membered saturated, nitrogen-containing heterocyclic ring that is optionally substituted by one or two C1-C8 alkyl groups, the heterocyclic ring being bonded to the benzene ring by a nitrogen atom in the ring; the heterocyclic ring may further contain one or two additional nitrogen atoms or an additional oxygen or sulphur atom. The method is characterised in that the reaction is performed in the presence of an alkaline metal hydroxide or alkaline metal carbonate.

Abstract:
Device, system, and method of interactive communications among mobile devices and Internet Protocol (IP) connected screens. A system enables rapid and efficient generation of an interactive application, that has a screen-side component able to nm on IP-connected screen, and that has a mobile-side component able to run on smartphones, tablets, smart-watches, and other mobile electronic devices. User feedback from an end-Dashboard Module user device, or aggregated user feedback from multiple end-user devices, interacts with and affects the interactive application as displayed on the IP-connected screen. The system enables the interactive application to run and to operate automatically at a sports venue, a digital billboard or digital sign, or at other suitable venues.
