  In the present work, we have carried out DFT simulations to investigate the
electronic and optical properties of a porphyrin-based 2D crystal named 2D
Diboron-Porphyrin (2DDP). We showed that it is possible to use strain to tune
the 2DDP electronic properties (from semiconductor to metal) depending on the
direction of the applied strain. 2DDP exhibits optical activity from the
infrared to the ultraviolet region. Similarly to electronic bands, strain can
also modulate the optical activity response. 2DDP can be a promising candidate
for some electro-opto-mechanical applications.
