Each year IUPAC endorses a large number of independently organized conferences, symposiums and workshops that cover a wide range of specialized topics in chemistry. Endorsement by IUPAC attests to the quality of the scientific program and indicates the host country’s assurance that scientists from all countries may participate. See program details. In addition, the calendar below includes webinars and workshops related to specific IUPAC projects or joint activities with associated organizations.

30th IUPAC Symposium on Photochemistry

Photochemistry is a key factor in many human endeavors, with energy and health as the most obvious areas of application. The conference, however, aims at broadly advancing the field of photochemistry for the future, both at the fundamental level and towards applications

The conference is the 30th in the series of IUPAC Symposia on Photochemistry. It serves as a meeting point for the community, and therefore has a broad program including all important topics in the field.Some subjects are listed below, but they are not intended as a limiting classification nor to exclude any other experimental or theoretical contributions related to the field.

CONFERENCE THEMES
·       Photocatalysis
·       Photochemical Reactions, Mechanisms and Intermediates
·       Frontiers in Photophysics and Spectroscopy (and Ultrafast Spectroscopy)
·       Single Molecule Photochemistry
·       Computational Photochemistry
·       Molecular Sensing and Imaging
·       Photochemistry in Material Science
·       Light Energy Conversion
·       Photobiology and Photomedicine
