Abstract
: We are all surrounded by chemical sensors. Nonetheless, the advances in Science and Technology, besides the regularly updated environmental laws are increasingly requiring the development of improved prototypes. Therefore, the development of molecular materials and Organic Electronics is making possible the conception of next generation sensors, potentially more versatile than those used so far. To report the interest of the topic, we will consider the phthalocyanines as key molecule/material for their evolution in the framework of both gas and liquid sensors.
