Pure organics with {room|space|area} temperaturephosphorescence (RTP) are urgently demanded in {advanced|sophisticated} optoelectronic andbioelectronic applications. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, {currently|presently|at present|at the moment} reported phosphors are mostlyaromatics and restricted to blue to orange colors. It remains an enormouschallenge {to achieve|to attain} red and near-infrared (NIR) RTP, {particularly|especially|specifically} for thosefrom nonaromatics. {Here|Right here} we demonstrate a series of cyclic imides derived fromsuccinimide, which can emit red (665, 690 nm) {and even|as well as|and also|and in some cases} NIR (745 nm) RTP withoutstanding efficiencies of {up to|as much as} 9.2%, {despite|regardless of|in spite of} their rather {limited|restricted} molecularconjugations. Such {unique|distinctive|special|exclusive|exceptional|one of a kind} emission {should be|ought to be|needs to be|must be|really should be|need to be} ascribed {to the|towards the|for the} presence of theimide unit and heavy atoms, {effective|efficient|successful|powerful|productive|helpful} molecular clustering, {and the|and also the|as well as the|along with the|plus the} electrondelocalization of halogens, which {not only|not just|not merely|not simply} {greatly|significantly|tremendously|drastically|considerably} facilitate intersystemcrossing, {but also|but additionally|but in addition} afford {significantly|considerably|substantially|drastically} extended through-space conjugation andrigidified conformations. These {results|outcomes|final results|benefits} pave the {way to|method to|approach to|strategy to|technique to|solution to} the rationalconstruction of red and NIR nonconventional luminophores {through|via|by means of|by way of} synergisticclustering and halogen effects.
