中文摘要	A simple route for fabricating highly ordered luminescent thin ﬁlms based on hybrid material of diblockcopolymer and europium complex, assisted with self-organization of polystyrene-block-poly(ethyleneoxide) (PS-b-PEO) diblock copolymer upon solvent annealing, is presented. PS-b-PEO self-organized intohexagonal patterns and europium complex of Eu(BA)3Phen was selectively embedded in PS blocks aftersolvent annealing in benzene or benzene/water vapor. During benzene annealing, the orientation of thePEO cylindrical domains strongly depended on the Eu(BA)3Phen concentration. In contrast, when thehybrid thin ﬁlmswere annealed inmixture of benzene and water vapor, high degree of orientation of thePEO cylindrical domains is more easily obtained, which is independent of Eu(BA)3Phen concentration.Furthermore, preferential interaction of PEO domains with water induces a generation of nanopores inthe hybrid thin ﬁlm. Atomic force microscopy (AFM), scanning electron microscopy (SEM), andtransmission electron microscopy (TEM) were used to characterize the long-range lateral order andphase composition of the hybrid thin ﬁlms. The ordered nanohybrid thin ﬁlms kept the ﬂuorescenceproperty of Eu(BA)3Phen and showed a strong red emission under the 254 nm light’s irradiation. Theﬂuorescence property was conﬁrmed by photoluminescence (PL) spectra.
