Introduction of Dr Mujahid Mustaqeem:

Chiral metal-organic frameworks (CMOFs), a new

family of chiral hybrid materials, have piqued the interest of researchers due to

their structural variety and flexibility, order nanopores, cost-effectiveness, and

distinct chirality properties. We have developed CMOF [Sr(9,10-adc)(DMAc)2]n based

on achiral building blocks [(9,10-adc)] to fabricate spin-polarized flexible

detectors that give a detectivity (D*) as high as 1.83 × 1012 jones, anisotropy

factor (gIph) is up to 0.38, photoresponsivity (Rph) and photogain (η) values of

CMOFs reach up to 6.0 × 105 (A/W) and 1.8 × 106, respectively superior to all

reported heterochiral MOF-based detectors. Additionally, we provided a different

strategy and developed spin-polarized LEDs based on chiral metal-organic framework

heterojunction and quantum dots (QDs) at room temperature without using

ferromagnetic connections or magnetic fields. The spin-polarized injected layer

was made of self-assembled monolayer (SAM)/Chiral-MOF ([Sr(9,10-adc)(DMAc)2]n)

film, which developed spin-polarized holes with spin orientation, impacting the

polarization and strength of circularly polarized electroluminescence (CP-EL). The

spin-QLED emitted CP-EL at a 12.24% efficiency, providing an ideal alternative for

generating new functionality for conventional QLEDs. Our approach is expected to

be very valuable, allowing us to provide a universal mechanism for generating

unrealized spin optoelectronic devices. These innovatively constructed devices

based on MOFs significantly contribute to the ongoing study of photonic devices
