(SIFigureS5). For example, theTPE-CMP@72hsampleexhibited
high luminescence in various solvents such as MeOH, dioxane,
THF, CH2Cl2, CHCl3, hexane, DMF, benzene, and water
(Figure 4A and S5). In sharp contrast, the linear analogue TPE-
LP@72h is almost nonemissive in CH2Cl2, CHCl3, and THF
(Figure 4A). In solvents such as MeOH, which causes chain
aggregation and suppresses rotation of the phenyl units, TPE-
LP@72h became weakly luminescent (Figure 4A). More signifi-
cantly, the TPE-CMP samples are highly luminescent even in the
solid state, without showing deterioration in light-emitting activity
or with any differences apparent between the samples prepared
over different reaction time (Figure 4B).

Taking all the above results into account, it is likely that the TPE-
CMP network acts to suppress the rotation of the phenyl units,
which is desirable for electronic conjugation, may also preserve the
fluorescence anisotropy, and allows long-range exciton migration
(Figure 3C). Several examples of luminescent TPE derivatives have
been reported in which solvent-induced aggregation is considered
to restrict the rotation of the phenyl units.6 We assume that a
network structure could similarly limit the rotation of the phenyl
units, because each TPE unit is effectively interlocked by covalent
bonds from four different directions. The similarly high ΦFL
values for the TPE-CMP samples synthesized over different
reaction time indicate the effectiveness in suppressing the phenyl
rotation. Such conformational confinement of the TPE units in
the network may promote conjugation and facilitate exciton
migration. On the other hand, in the linear TPE-LP, two freely
rotatable phenyl groups remain for each TPE repeating unit,
which accounts for the low luminescence activity. Therefore,
unlike the small TPE molecules and its linear polymer analogues,
which require external conditions such as aggregation to tem-
porarily “stabilize” their fluorescence, the TPE-CMP structure
suppresses the rotation of the phenyl units by virtue of its
interwoven network, thus providing intrinsic luminescent activity.
In summary, we have described a strategy for the synthesis of a
highly luminescent conjugated polymer based on a conjugated
microporous architecture. The CMP network with three-dimen-
sionally interlocked skeleton suppresses the rotation of building
blocks, promotes π-electronic conjugation, facilitates exciton
migration, and enhances luminescence irrespective of the solvent
and material state. These positive “CMP effects” on π-electronic
conjugation feature CMPs as a unique platform for the design
of de novo conjugated materials, which can be difficult to achieve
with conventional linear polymers. Because emission losses induced
by rotation are ubiquitous among chromophores, this network
approach can be generalized for the development of various efficient
light emitters and wavelength converters.
