Gas sensors and compounds suitable therefor |
摘要 |
A gas sensor has a gas sensing component which permits measurement of a change in optical absorption and, optionally also a change in electrical conductivity on exposure to an environment containing certain gases. The gas sensing component comprises a metal bis aromatic macrocycle which may be a new mixed rare earth metal bis tetrabenzoporphyrin or tetrabenzoazaporphyrin.
