A new chromenoquinoline-based thiol probe is described. The probe displayed 223-fold enhancement in fluorescence intensity upon sensing cysteine. The cell permeability and the imaging of thiols in living cells are demonstrated.

About this collection
The Chemical Research Society of India (CRSI) was established in 1999 and currently represents thousands of Indian chemists who are actively engaged in the pedagogy, research, and promotion of Chemistry. The main objectives of this Society are to nurture, recognize, and encourage talent in the chemical sciences and to expand the overall quality of chemical education at all levels in India.
The CRSI and the Royal Society of Chemistry (RSC) have a decade long collaboration. As part of this, the CRSI organizes annual CRSI-RSC joint symposia along with the National Symposium of Chemistry. These meetings collect expert speakers from both the UK and India, with the 13th meeting in this series being recently held at IIT Madras, Chennai, on February 7, 2019.
ChemComm is the Royal Society of Chemistry’s most cited general chemistry journal, and it has an impeccable tradition of publishing exciting new research findings of exceptional significance across the sub-disciplines of the chemical sciences. It is a much preferred destination for Indian chemists to showcase their best results and as a result the annual publications in ChemComm from India have more than tripled in the 10 years of the CRSI-RSC collaboration. It is also worthy to note that there are two Associate Editors from India on the Editorial Board of ChemComm.
As a tribute to the strong cooperation between CRSI and RSC, we are very pleased to present a special ChemComm web collection to commemorate the 20th Anniversary of the CRSI. The papers showcased in this web collection are a representation of the wide authorship from India and span a broad spectrum of research areas. We are grateful to ChemComm for their enthusiastic support in bringing out this special collection and for their kind offer to serve as Guest Editors.
We hope that the CRSI-RSC cooperation will continue to flourish for decades to come and reach new heights of professional partnership and knowledge dissemination in the chemical sciences.
