2 (1)Experimental Procedures Unless otherwise noted, all reagents were obtained from commercial suppliers and used without further purification. 1 H NMR spectra was measured on a Bruker AVANCE-300 NMR Spectrometer. X-ray powder diffractions were measured on a Panalytical X-Pert pro diffractometer with Cu-Kα radiation. Elemental analyses (C, H, N) were obtained on a PerkinElmer 240 elemental analyzer. The thermogravimetric analysis (TGA) was carried out between room temperature and 600 C in a static N 2 with a heating rate of 10 C/min. Photoluminescence spectra were measured on F-2700 fluorescence spectrophotometer. The fluorescent detections of metal ions or aromatic compounds were performed by the incremental addition of analytes (0 to 70 µl) to 3 ml of emusions of UPC-17. The emusion was obtained by adding 2 mg of UPC-17 into 3 ml of solvent, and ultrasonically dispersing 20 minutes. The 10 mmol dm -3 of analyte was prepared by using the same solvent with the detecting emulsion. - S2 -

3 (2) Synthesis of ligand and UPC-17 Synthesis of H 2 ADDA. A 250 ml three-necked flask with magneton was charged with a mixture of 9,10-dibromoanthracene (3.36 g, 10 mmol), Pd(OAc) 2 (90 mg, mmol) and tris(o-tolyl)phosphine (580 mg, mmol). The flask was degassed and filled with nitrogen, which was repeated for three times. Waterless Et 3 N (80 ml) were added by a syring under nitrogen. After this, methyl acrylate (2.5 ml, mmol) was added to the solution. The reaction mixture was heated to 100 in an oil bath for 2 days under N 2 atmosphere. After the mixture was cooled to room temperature and concentrated with a rotary evaporator, it was extracted with CH 2 Cl 2 and washed three times with H 2 O. The organic layer was then dried with MgSO 4, and the solvent was removed with rotary evaporator. The resulting crude product was purified by column chromatography (CHCl 3 as the eluent). The product was obtained after removal of the solvents (2.4 g, 69.4% yield). 1 H NMR (400 MHz, CDCl 3 ): δ 8.61 (d, 2H); 8.25 (q, 4H); 7.54 (q, 4H); 6.43 (d, 2H); 3.93 (s, 6H). - S3 -

5 To a suspension of (2E,2'E)-dimethyl 3,3'-(anthracene-9,10-diyl)diacrylate (2.4 g, 6.9 mmol) in 30 ml THF was added 30 ml MeOH and 40 ml 3M aqueous KOH solution. The mixture was heated at 60 overnight. After this, the mixture was cooled to room temperature, it was poured into an ice/hcl mixture, then followed by filtration, and washed several times with H 2 O. The product (2.08 g, 65.4%) was obtained after the organic layer was collected and the solvent was removed via rotary evaporator. 1 H NMR (400 MHz, DMSO-d 6 ): δ (s, 2H); 8.50 (d, 2H); 8.23 (q, 4H); 7.64 (q, 4H); 6.34 (d, 2H). - S5 -

6 Synthesis of UPC-17. A mixture of Ba(NO 3 ) 2 (26 mg, 0.12 mmol), H 2 ADDA (3 mg, 0.01 mmol), 2 ml of DMF-EtOH-H 2 O (v/v/v = 5:2:1) was sealed in a pressure-resistant glass tube, heated to 90 C during 8 hours, kept at 90 C for 48 hours, and then slowly cooled to 30 C during 10 hours. Pale yellow crystals were collected, washed with EtOH and dried in air (yield: 70%). Elemental analysis calcd (%) for UPC-17 (Ba 5 (ADDA) 5 (EtOH) 2 (H 2 O) 3 5DMF/ Ba 5 C 119 H 113 O 30 N 5 ): C 51.42%, H 4.10%, N 2.52%; found: C 51.08, H 3.99, N 2.54 %. - S6 -

7 (3) Crystal structure determination of UPC-17 Crystal structure determination of UPC-17: Single-crystal X-ray diffraction was performed using an Aglient technologies SuperNova Atlas Dual System, with a (Mo Kα λ = Å) microfocus source and focusing multilayer mirror optics. Structure was solved by direct methods using SHELXTL and refined by full-matrix least-squares on F 2 using SHELX-97. Non-hydrogen atoms were refined with anisotropic displacement parameters during the final cycles. Hydrogen atoms were placed in calculated positions with isotropic displacement parameters set to 1.2 U eq of the attached atom. Crystallographic data (excluding structure factors) for the structures reported in this paper have been deposited in the Cambridge Crystallographic Data Center with CCDC Number: S7 -
