low absorptivity is still a common challenge in the development of new luminescent materials. in article number 2306616, lei zheng, feng xu, guorui jin, ben zhong tang, and co-workers report a simple, efficient and universal design strategy by introducing a gold(i) unit to luminescent molecules, especially nir-ii molecules, to elevate their absorptivity for intensified nir-ii emission and synergized multimodality therapy.
